pin

Search for the memory with the mem0_memory tool using action search, then re-add its content with a [PINNED] prefix and delete the original entry. The marker tells dream consolidation to skip it during pruning.

Find the pinned memory by search or ID, create a new memory with the same content but without the [PINNED] prefix, then delete the pinned version. The memory remains stored but is no longer protected from pruning.

Yes. Use the mem0_memory tool with action add and content formatted as [PINNED] followed by your text. This creates a new memory that is immediately protected from consolidation pruning.

Pinned memories are skipped during pruning because the [PINNED] prefix signals the consolidation process to exclude them. They persist indefinitely until explicitly unpinned or deleted.

Avoid pinning temporary or frequently changing information, since pinned memories are never pruned and can accumulate stale data. Reserve pinning for stable facts like core preferences, major decisions, or immutable personal details.
